I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...
The LM35 is a precision integrated-circuit temperature sensor (PTAT; proportional to absolute temperature) manufactured by Texas Instruments (https://www.ti.com ...
Arduino-based multi-sensor dashboard that measures temperature, ambient light, and distance, then shows the temperature on a 4‑digit 7‑segment display, logs data to serial (for PuTTY), and drives a ...
